This looks really cool. Was audiosurf an inspiration by any chance? Loved that game

Sure was! I played a lot of it as well :]The original idea came from my friend, who looked at this video and said it would make for a good game (not really saying what kind of game though):

I immediately thought of the basic idea for the game, made a quick prototype and since it was fun, decided to finish it.In fact, the original (desktop) version was written in C# and is actually a heavily modified version of the program I wrote for that video. 3D graphics programming is fun!
